Tom S Chang MD on Digital Eye Strain Proactive Eye Care

Tom Chang, MD Explains What Digital Eye Strain Is


Tom Chang is a medical doctor at the Huntington Hospital in Pasadena, California, who has over twenty years of experience in General Ophthalmology. He describes in an article what digital eye strain is. Tom S Chang MD explains it as being a vision-related health problem that usually occurs from extensively using devices that emit blue-light frequency, including laptops, cell phones, tablets, and other digital technology devices. 


Specialized ophthalmologist Tom S Chang MD further elaborates that this disorder can also impact other parts of the body, including experiencing neck and shoulder discomfort, and also headaches in a variety of severity levels, and symptoms can last even after the period of digital use is complete. Manifestations of digital eye strain over-exposure symptoms do include blurred vision, tired eyes, and dry eyes. Tom S Chang MD has noticed additional manifestations and symptoms may include excessive glares, poor posture, poor lighting, and an unsuitable view of distances. 


Another issue is that individuals with uncorrected or vision problems under-corrected may experience worsened conditions of digital eye strain conditions because of the eyes being forced to overcompensate for periods of limited vision. Diagnosis of digital eye strain includes proactive methods such as a comprehensive eye exam and utilizing the eye healthcare expert recommended 20/20/20 rule. According to Tom S Chang MD, an eye exam can help to reveal the effects of blue-light digital eye strain. The 20/20/20 rule is to take a 20-second break by looking away from your devices every 20 minutes at a distance of at least 20 feet away. Frequently blinking can also help to minimize the effect of dry eyes. 


Tom S Chang, MD Explains How to Proactively Care for Your Eyes 

The eyes are one of the five vital and basic human senses, and they work with other parts of the body that are responsible for more than just sight. Exposure to the sun is a major problem for the eyes. Tom S. Chang MD recommends regularly wearing sunglasses that provide 100% UVA and UVB ray protection while outdoors. UV rays are still present, even on cloudy days, so wearing sunglasses on cloudy days is necessary. Wearing wraparound protective eyeglasses and protective goggles that are ANSI-approved with an Z87 rating help to protect the eyes from entry of particles at every angle.
